Identification Biometrics Unlocking Method: Sweat Certification [Full Text]

Technology Trends As people become more aware of information security, the unlocking function of smart terminals has become more and more important. From pattern unlocking and password unlocking to the development of fingerprint unlocking in recent years, the recently launched iPhone X even launched a new “Face ID”—face recognition unlocked.

However, the researchers did not stop on the road to explore the unlocking of biometrics. Not long ago, Associate Professor of Chemistry at the State University of New York at Albania published an article in ChemPhysChem, discussing a new method for identifying biometric unlocking on wearable smart devices such as smart phones or smart watches. Sweat certification. Japan's livedoor news network recently reported this new technology.

Most smart phones now use fingerprint authentication, and the stability of the face recognition system on iPhone X is not high. According to the associate professor's claim, sweat certification is better than the above in accuracy.

The reason for this is that "sweat has fingerprints and irises, and it has unique personal characteristics." This plays an important role. The associate professor looks at the secretions of the skin - the amino acids that make up sweat - and finds that it is like a fingerprint. Each person's sweat has its own unique and inherent characteristics. From this point of departure, he proposed the "sweat certification" program. By storing these characteristic information on the mobile device, you can use it when unlocking the mobile phone and other devices that require authentication.

However, the determination and collection of sweat information is not as fast as fingerprint authentication.

To use sweat certification, you first need to determine the user's sweat status at different times during the day. Because different people have different sweat conditions throughout the day. For example, comparing the amount of sweat at 2 a.m. with those who work at night and those who go to work during the day, there should be no small difference. In addition to time, different ages, genders, races, physical characteristics, occupations, etc. can also lead to different compositional rates and amounts of sweat. The sweat information collected in this day is stored. When people hold the smart phone in their hands or wear the smart watch on their wrists, they can perform identification and certification.

The associate professor said that such sweat certification is not only more accurate, but also can provide convenience for users who cannot perform fingerprint authentication or face recognition difficulties. As a result, people who can easily use biometric authentication have expanded.

For the current mainstream authentication system, the associate professor said: “It's easy to be seen with a password, and how much can be found by using the device to get fingerprints to unlock online. There are too many cases for face authentication. Reports that cannot be identified effectively."

According to the experiments of their institute, the current sweat certification has no related problems and can always be used effectively. (Original title: Face recognition is not the most advanced? Sweat recognition will be more accurate)
